Jens Johansen 211ad9acb1 [CFE] Don't mark procedures as async when not using await 
This CL removes async markers where await wasn't used.

In a few cases this also meant the ability to make the procedure not
return a future at all.

Also - at least on the VM with my benchmark run on my PC - returning
new Future.value(whatever) in a non-async procedure is faster than
returning whatever in an async procedure.

TEST=CI and existing tests.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
